Topic: "IOError: [Errno 30] Read-only file system" when installing SME 8 from USB

[avamk]

Hello,

By using the instructions in this post, I managed to make my 8.0GB USB flash drive boot the latest SME Server 8 beta 6 ISO image. The installation program starts when I boot from USB, and configuration of install options worked fine.

After pressing "Install now", the installation starts, then ends with a python exception error: IOError: [Errno 30] Read-only file system

I tried it twice (with different USB sticks) and got the same error, what does this mean and how should I alleviate this problem?

Thanks!!

why don't you install it via cd?

Unfortunately, the box I am trying to install it in, a VIA Artigo A1100, does not have an optical drive, and I don't have an external one either. So is there any hope of installing from a USB stick? Thanks!!

AFAIK that feature hasn't been developed.

It hasn't exactly been developed, but you can boot from a USB pen and install the latest SME Server 8b6 as I have done so on occasions where CDROM support hasn't been available.  Google is your friend

.....Google is your friend

A Google search is what led me here.

But like I said before, after following the install from USB instructions posted in this thread, I get "IOError: [Errno 30] Read-only file system" during installation. Any ideas why?

How did you do it?

I guess it is large enough to be considered by the operating system as a disk that is part of the software raid array it is trying to create. What is the size of the USB drive you are using? Perhaps you can try and manually create the partitions in order to take care not to include the USB drive?

I have a 8.0 GB USB drive. The hard drive I am trying to install SME 8 on is 40 GB. Should I partition the hard drive AND the USB drive in some way? And should I do it BEFORE running the installation program (perhaps via fdisk)? If so what format? ext3?

Sorry about all the questions, I am quite new to SME.

During installation there should be an option to manually partition or review the partition IIRC.

No problem, we all have to start somewhere...

This is the tool I used to get a usb SME Server booting from USB stick successfully and installed (very quickly too )...

Little bit of "know-how" is required.

Hi,

The issue here is that the USB stick is > 4G which is where the operating system says it is no longer a removable drive and is a fixed drive suitable for install.  The current installer upon seeing this drive tries to make it part of the raid array it creates and by doing so renders the USB drive corrupt (and thus fails to read-only).

You can use the installer cmdline options to exclude the drive so that it will install correctly, or you can wait for the next released ISO that has a fix in it to automatically exclude any drive/device that is being used to install.

If you mean these options I fail to see how to do so, also the relevant bugs do not help me much:

http://bugs.contribs.org/show_bug.cgi?id=5850

Perhaps you can show us how?

Yeah, please tell us what to do.

I tried the boot options "sme raid=[none] drives=hdb", "sme raid=[none]", and "sme drives=hdb", none worked. I even tried to use the rescue mode to create a small partition on the hard drive (format it ext3), place the SME 8 iso in that partition, and used it when asked during install from USB stick, but it still didn't work.

BTW, I am attaching a photo I took of the exact error that occurs. Its always the same file, same error.

Still reading the other bug
It eventually takes you to the same place ie
http://wiki.contribs.org/Booting#Installer_Boot_Options
the SME8 options having been merged into that document

and the description of how to use the options here
http://bugs.contribs.org/show_bug.cgi?id=5316#c13

Yes, Mary I have noticed they all point to the same page. However I have not been able to deduce how I can exclude one drive from the installation process.

If I understood things correctly the new installer (still to be released) should have no problem anymore as it will automatically exclude drives from which the installer is run. The drives option is only to specify drive types IMHO.

Looking some more through bug 5316, perhaps this might be the clue: http://bugs.contribs.org/show_bug.cgi?id=5316#c27. It mentions the nousbstorage option, which fails on the http://wiki.contribs.org/Booting#Installer_Boot_Options page, perhaps as it might be a more general boot option (not only applicable to installer) as listed here: http://www.centos.org/docs/4/html/rhel-ig-x8664-multi-en-4/ap-bootopts.html
(although for el4 I guess most are that general that they will work in EL5 as well).

Quoting from the bug report at http://bugs.contribs.org/show_bug.cgi?id=5316#c13
"The installer without anything being passed should behave identically for disks
< 10 with the exception that it won't include any device that is housed on a
drive that needs the usb-storage or spb2 module.
If you want to include drives that are on USB or firewire you must use the
drives= option and specify all drives (not just the usb/firewire drives) that
you want to use."

The drives option is only to specify drive types IMHO.

Not according to the above text. It says list all drives you want to include. So by process of elimination (reverse logic maybe), if you list all drives except one, then that one drive is excluded.

ie
You do not actually list the drive you want to exclude.
Instead you do not list the drive you want to exclude.
Make sure you list all other drives so they are included.

Yes, but that is after the rework of the installer, which is not released AFAIK, the bug is still in NEW state, so that will not work with the current ISO.

As I'm reading it (I have not tried it), the command line will allow you to include all drives (to install the OS to) except the USB boot/install drive (which has the install iso on it), which can be performed now (on sme8) before the next iso release.
So the lack of inclusion of the install USB drive in the switch, will exclude it (stop the installer trying to install the OS onto it).

Do you not read it that way ?

[slords]

If you have three hard drives (hda,hdc,sda) with sda being your usb  drive you are trying to install from you can install using either of these startup lines:

sme drives=hda,hdc
sme exclude=sda

The installer changes that include these options should be part of the 7.5.1 and 8.0b6 ISOs.  There is an update to the installer that will be part of the next ISOs that will automatically exclude any drive that contains the install media or ks files.

I tried "sme drives=hdb" (my sdd harddrive is hdb) but it didn't work. Will try "sme exclude=sda" when I have access to my box on Monday.

Any idea on when the next ISOs will come out???

Thanks so much for all the help/discussion so far!

[avamk]

I tried both "sme exclude=sda" and "sme exclude=sda,sda1" but installation still ends with the same error. Is there anything else I can do? Or do I have to wait for the next release?
